Show ALLOW FOR FUTURE TRAFFIC Count of Automobiles on Number of Roads in Tennessee Shows Surprising Sur-prising Fact. (Prepared by the United States Depa-rtment of Agriculture.) In building a road liberal allowance should be made for future increase in traffic, says the bureau of public roads of the United States Department of Agriculture. A traffic count conducted by the bureau In co-operation with Tennessee officials on a number of roads in Davison county, in which Nashville Is located, shows surprising facts when compared with a similar count in 1916. During this period automobile au-tomobile registrations have doubled, while the number of motor vehicles on the roads is fivg times as great as In 191G. In 1916 horse-drawn and motor-vehicle motor-vehicle traffic were almost equal In volume. In 1921 horse-drawn traffic had increased only slightly In volume and constituted 1G per cent of the traffic, motor vehicles constituting 84 per cent. Observations in this and other countries coun-tries lead to the conclusion that volume vol-ume of traffic may increase in much greater proportion than the number of motor vehicles and will also depend to a large degree on the condition of improvement of the road and on the economic conditions in the adjacent territory. |
